The experimental bullet train, which can reach top speeds over 310 mph, was debuted on December 25th in Qingdao in Shangdong Province. Inspired by the shape of ancient Chinese swords, the aerodynamic CRH series train can deliver 22,800 kW of power to its load. The sword-train, created by CSR Corp. Ltd. is part of a “faster test train project” aimed at advancing an already impressive national railway system. With this latest feat of engineering, China is again demonstrating its commitment to creating the infrastructure that will sustain the emerging nation in the 21st Century."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
